Conduction and the Star-Formation Threshold in Brightest Cluster Galaxies
G. M. Voit, K. W. Cavagnolo, M. Donahue +3
Current models of galaxy evolution suggest that feedback from active galactic nuclei is needed to explain the high-luminosity cutoff in the galaxy luminosity function. Exactly how…
An Entropy Threshold for Strong H-alpha and Radio Emission in the Cores of Galaxy Clusters
Kenneth W. Cavagnolo, Megan Donahue, G. Mark Voit +1
Our Chandra X-ray Observatory archival study of intracluster entropy in a sample of 222 galaxy clusters shows that H-alpha and radio emission from the brightest cluster galaxy are…
Bandpass Dependence of X-ray Temperatures in Galaxy Clusters
Kenneth W. Cavagnolo, Megan Donahue, G. Mark Voit +1
We explore the band dependence of the inferred X-ray temperature of the intracluster medium (ICM) for 192 well-observed galaxy clusters selected from the Chandra Data Archive. If t…
Star Formation, Radio Sources, Cooling X-ray Gas, and Galaxy Interactions in the Brightest Cluster Galaxy in 2A0335+096
Megan Donahue, Ming Sun, Christopher P. O'Dea +2
We present deep emission-line imaging taken with the SOAR Optical Imaging Camera of the brightest cluster galaxy (BCG) in the nearby (z=0.035) X-ray cluster 2A0335+096. We analyze…
Abundances of s-process elements in planetary nebulae: Br, Kr & Xe
Y. Zhang, R. Williams, E. Pellegrini +5
We identify emission lines of post-iron peak elements in very high signal-to-noise spectra of a sample of planetary nebulae. Analysis of lines from ions of Kr and Xe reveals enhanc…
Entropy Profiles in the Cores of Cooling Flow Clusters of Galaxies
Megan Donahue, Donald J. Horner, Kenneth W. Cavagnolo +1
The X-ray properties of a relaxed cluster of galaxies are determined primarily by its gravitational potential well and the entropy distribution of its intracluster gas. That entrop…
